JQLite - The query language for JSON

#programming #typescript #javascript #json

Hey guys!

Created a simple query language for JSON in Typescript.

This is a learning/hobby project to know more about parser, and how languages work.

Features:

Basic query selection
Fallback Mechanism
Wildcard support
Array Slices
Multiple Key Selection
Key Omission
Single Key Omission
Functions
Comparison Operators
Conditions
Configurable

Here's a simple guide to get started:

import { config, data, query } from 'jqlite-ts';

// Load the data from a JSON file
data.load("./data.json");

// Override the default config
config.set({
  fallback: "No data found!"
});

// Run the query
query.run("$.friends[*].(name, age)", (result) => {
  console.log(result);
});

Few examples:

Get the list of all products which has an average review more than 4
$.products[?(@.reviews.#avg() > 4)]
Filter the products which has a price greater than 1500.
$.products[?(@.price > 1500)]
Get the list of all delivered items
$.orders[?(@.status.#equals('delivered'))][*].items
